As far as I understand, you want the H2 tags inside category descriptions do not start a new line, but get displayed inside the line which they are declared in.

If so, you should add the following CSS rule (you may use the ThemeTweaker module to do this):

.category-description h2 {
display: inline;
}

Also, I've noticed that you use "<font>" tags. These are deprecated now, so it makes sense to remove them and configure the color in the above CSS rule.
